. The invention relates to a heddle bar securing device for mounting a horizontally extending flat heddle bar to a horizontally extending rail of a heddle frame in a loom Iconstruction.

The primary object of the invention is to provide a simple form of heddle rod support or lock hook which will provide for a more positive engagement with the heddle bar than is afforded by present known similar devices.

The present disclosure particularly features a form of support which will provide minimum width `land maximum rod bearing surfaces and at the same time to provide such a support as will not cause excessive parting of the heddles and which will permit the passing of the heddles fromone side of the support to the other, while theheddle frames are in the loom.

-A still further object of the invention is to provide a form of support in the form of a clamp with wide bearing clamping surfaces for engaging the heddle bar and which will maintain firm engagement therewith even under conditions where the parts become worn in use. i

Still another object of the invention is to provide a structure which will permit a ready and quick insertion and removal of the heddle bar from the support in case it is desired to replace the heddle bar in use with a different one or one of different size.

Various other. objects and advantages of the invention will bein part obvious from an inspection of the accompanying drawing and in part will be more fully set forth in the following particular description of one form of device embodying the invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

VIn the accompanying drawing:

Fig. l is a view in front elevation of a preferred embodimentof the invention shown screwed into a heddle frame rail shown in dotted outline and shown engaging and supporting a heddle bar and also showing the retaining bar in full lines in its I normal clamping position and in dotted lines swung into an inoperative position;

,Fig. 2,is` an edge view of the device shown in Fig. l with the retaining barvsprung from its full line into its dotted line position; and

Fig. 3 is a vertical sectional view taken axially of the device shown in the preceding figures.

In the drawing there is represented diagrammaticallya heddle frame of a loom by ahorizontally extending rail A and a horizontally extending flat heddle bar B, inxthisparticular case shown in Fig. 1 than thickness considered horizontally as shown in Figs. 2 and 3.

The device I0 lfor supporting the heddle bar lfrom ,the rail yincludes a main supporting member- II comprising an upper plate I2 having a straight lower edge I3 forming the upper shoulderA outlining a recess hereinafter described for receiving the heddle rod B. 'I'he plate I2 is provided vmid-length with a flat pivot bearing portion I4 yand thereabove with an extension I5 forming a screw by means of which the device is screwed into the rail A wherever it is desired to mount such a heddle bar support. The axis of the screw I5, prolonged downwardly, passes across the recess I8' parallel to its rear wall I9,

`so that after the screw is located in position, it

may be rotated slightly in either direction about its own axis to bring the flat rear wall I9 parallel tothe plane of the adjacent face ofthe heddle rod B. The main supporting member Il also includes a plate I6 depending from the plate I2 and provided on its front side with a straight edge I'I forming av lower shoulder or supporting ledge. The space between the shoulders I3 and I1 forms a recess I8 of rectangular or rectilinear form with a flat rear wall I9. The plates I2 and I6 coact to form an element'or jaw of a clamp which constitutes the lower portion of the main supporting member II. A retaining bar 20 constituting a keeper is pivotally connected to the plate I2' at its bearing surface I4, as hereinafter described, and normally extends lengthwise of the main supporting member, and across the recess and' projects for a vshort distance below the plate nII to provide an extension 2| forming a iinger piece for manipulating the retaining bar.

y The retaining bar 20 is pivotally and resiliently mounted on pivot pin 22 provided at one end with a head 23 and at the opposite end with spring washer 24 which acts'through the head 2,2 to hold the retaining member 20 in whatever position it may be swung. The upper end of the member 20 is provided with arestraining mean-s for locking the bar 20 in its normal position as shown in full lines in the several figures. This restraining means includes a knife-like edge 25 projecting rearwardly from the upper rear face of the bar 20 and held in slot 26 formed in the bearing portion I4. With this construction it is appreciated that normally the bar 20 will be held in position against any accidental movement therefrom but -is responsive to a forceful swinging movement about itspivotal support to shift thebar 20 from the full line into the dotted line position shown in Fig. 1.

The construction also permits the engagement of the nger piece 2| to move the lower portion of the bar 20 outwardly at right angles to the plane of the bar B and in the direction indicated by the arrow in Fig. 3, from the full line to the dotted line position shown in Fig. 2 so as to slip a heddle bar B into the recess by lifting the bar edgewise upwardly between the lower end of the bar 20 and plate I6 until it is received in the recess as shown in Fig. 2 after which the retaining bar is permitted to snap back under the action of the resilient washer 24 into the full line position shown in Fig. 2.

The retaining bar 20 is provided midlength with an offset portion 26 normally faces the recess |8 and in the absence of the heddle bar B intrudes more or less into the recess to engage the outer face of the heddle bar. By the use of this oiTset it is, of course, possible to mount in the recess heddle bars having a thickness less than the depth of the recess and at the same time hold such thin heddle bars snugly against the rear wall i9 of the recess. It is even possible to mount in the recess heddle bars having a thickness of material greater than the depth of the recess for the parts are so proportioned in the length of the shank of the pivot pin 22' and in the construction of the spring 24 to insure the bearing or clamp-ing action herein featured even though the heddle bar projects beyond the outer face of the main, support.

It is particularly noted that the heddle bar snugly fits in the recess so that there is provided a large bearing area between the rear side of the heddle barv and the support equal to the full width of the support. The shoulders I3 and Il provide edge bearings for the heddle bar so that possibility of the heddle bar rotating about a horizontal axis is avoided. As the elements forming the jaw clamp are firmly held together by virtue of the resiliency inherent in the washer.24 and thus possibility of the heddle bar being jolted out of its support is avoided, at the same time a structure is provided which will permit the ready installation and displacement of the heddle bars in place either by swinging the bar 20 about itsv axis to clear the recess as indicated by the dotted line showing in Fig. 1 or by springing the bar 20 forwardly as shown by the arrow in Fig. 3, both operations being effected by simple manual operation and without necessity of using tools to demount the holding parts.

While there have been shown, described and pointed out in the annexed claims, certain novel features of the invention, it will be understood that jvariousiomissions', substitutions and changes in the form and details of the device illustrated and in its operationmay be made by those skilled in the art without departing from the spirit of the invention.
